A transform fault or transform boundary, is a fault along a plate boundary where the motion is predominantly horizontal. [1] It ends abruptly where it connects to another plate boundary, either another transform, a spreading ridge, or a subduction zone . [ 2 ]

At the triple junction each of the three boundaries will be one of three types – a ridge (R), trench (T) or transform fault (F) – and triple junctions can be described according to the types of plate margin that meet at them (e.g. fault–fault–trench, ridge–ridge–ridge, or abbreviated F-F-T, R-R-R).
Slip along the Owen fracture zone is occurring at 2 mm (0.079 in)/yr, the slowest rate on Earth, which means the Arabian plate moves northward faster than the Indian plate (4 vs. 2 mm/yr). [2] In some usages, the name Owen Transform Fault is used to denote the short section between the end of the Aden-Sheba ridge and the Carlsberg Ridge. [3]
A leaky transform fault is a transform fault with volcanic activity along a significant portion of its length producing new crust. [1] In addition to the regular strike-slip motion observed at transform boundaries, an oblique extensional component is present, resulting in motion of the plates that is not parallel to the plate boundary.
An interplate earthquake event occurs when the accumulated stress at a tectonic plate boundary are released via brittle failure and displacement along the fault. There are three types of plate boundaries to consider in the context of interplate earthquake events: [4] Transform fault: Where two boundaries slide laterally relative to each other.
The Azores–Gibraltar transform fault (AGFZ), also called a fault zone and a fracture zone, is a major seismic zone in the eastern Atlantic Ocean between the Azores and the Strait of Gibraltar. It is the product of the complex interaction between the African , Eurasian , and Iberian plates. [ 1 ]
The Panama fracture zone is a major, active right lateral-moving transform fault and associated inactive fracture zone which forms part of the tectonic boundary between the Cocos plate and the Nazca plate, the Cocos–Nazca spreading centre.
